I have SL on both of them so i don't know if that would be an issue or not.

here is the basic procedure i used:

download MLB

set up MLB on the "master" computer, it had my tank and healer. I set up all my blacklist / whitelist keys and teams and such. MLB seems to save all this info in the application rather than in a preferences file.

After it was all set up i copied the application from the "master" computer to the "slave" computer. I think i copied over the network with file sharing but a usb key would probably work too.

fire up MLB on the "slave" computer and add the wow's from that computer.

I think i enabled / disabled broadcast and black / white listing a few times and it started working between the computers.


a few notes:

I launched my wow applications on my own and added them the MLB after they were launched.

I think i had my firewall on, but you may want to try it with the firewall off for troubleshooting if it still doesn't work for you.

Make sure you have Bonjour operating on your system, it should be by default i think (i am not even sure it can be turned off now that i think about it)

You should be able to see the other computer in the finder if you have file sharing turned on for both computers. This will ensure that you don't have any network problems that might keep the 2 computers from seeing each other.

Are you using Airport / wireless or a wired connection. You may want to try a wired connection for both computers if that is possible.

I hope some of this helps, let me know if you have any luck or not.
